LOCOMOTlVE-CAB WINDOW.

SPECIFICATION forming part f Letters Patent No. 276,907, dated May 1, 1883. Application filed December 23, 1882. (No model.)

To all whom it may concern Be it known that 1, JOHN SHIELDS, of Hancock, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Windows for Locomotive- (Jabs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying'drawings, which form a part of this specification, and in which- Figure l is a perspective view of my improved window for locomotive-cabs, and Fig. 2 is a detail view of the same.

Similar letters of reference indicate corre sponding parts in both the figures.

My invention has relation to windows for locomotive-cabs; and it has forits object to provide a window which may be opened, so as to enable the engineer to have a free lookout along the track, and at the same time protect him against the weather. and smoke and cinders from the engine, while it may be slid forward, if desired, in the manner usual in this class of windows, leaving the window entirely free and open. To this end [make a window of a construction set forth in the following description, and pointed out particularly in the claims.

In the accompanying drawings, the letter A indicates part of the cab-frame, which is provided with a fixed window, B, and a sliding frame, 0, sliding in ways I) of the frame, and in which is hinged a window, E. The hinges F of this window are sunk into the frame, so as not to interfere with the sliding of the window and its frame. A bar, G, bent in the end,

is hinged to the swinging window E, and its.

bent end is adapted to engage in a series of staples or bails, H, upon the inside of the bottom piece of frame (3. By changing the bent end of bar G from one of these bails to another the swinging window may be opened at any desired angle. Upon the inside of the bottom piece of the frame is a staple, I, adapted to receive the bent end of bar G, and to hold the sliding frame either closed or slid back in front of the fixedwindow, while a turn-button or swivel, J, serves to hold the swingingwindow closed. In this manner it will be seen that the swinging window may be opened at any desired angle, protecting the engineer in looking out, while, when desired to have a perfectly free lookout, or when the engine is passing objects nearto the track, which might come in contact with the window, it may be closed and slid forward in its ways in the same manner as windows usually employed in locomotive-cabs.

A sector-shaped plate, K, may be hinged to the upper edge of the swinging window in such a manner that it may be extended to cover the opening on top betweenthe swinging window and the sliding sash, forming aprotection from objects from above, and be folded down when it is desired to slide the window forward.

bar G, and turn-button J, all constructed to operate as and for the purposes shown and specified. t

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
